In the same way that the conic sections are studied in two dimensions, the 17 quadric surfaces, ., the ellipsoid, paraboloid, and elliptic paraboloid, are studied in solid analytic geometry in terms of the general equationax2+by2+cz2+dxy+exz+fyz+px+qy+rz+s=0. The methods of analytic geometry have been generalized to four or more dimensions and have been bined with other branches of geometry. Analytic geometry was introduced by Ren233。 and the attempt to transfer pure emotion directly onto the canvas. The movement had an inestimable influence on the many varieties of work that followed it, especially in the way its proponents used color and materials. Its essential energy transmitted an enduring excitement to the American art scene. Science and technology is quite a broad category, and it covers everything from studying the stars and the plas to studying molecules and viruses. Beginning with the Greeks and Hipparchus, continuing through Ptolemy, Copernicus and Galileo, and today with our work on the International Space Station, man continues to learn more and more about the heavens. From here, we look inward to biochemistry and biology. To truly understand biochemistry, scientists study and see the unseen by studying the chemistry of biological processes. This science, along with biophysics, aims to bring a better understanding of how bodies work – from how we turn food into energy to how nerve impulses transmit. analytic geometry, branch of geometry in which points are represented with respect to a coordinate system, such as Cartesian coordinates, and in which the approach to geometric problems is primarily algebraic. Its most mon application is in the representation of equations involving two or three variables as curves in two or three dimensions or surfaces in three dimensions. For example, the linear equation ax+by+c=0 represents a straight line in thexyplane, and the linear equation ax+by+cz+d=0 represents a plane in space, where a, b, c, and dare constant numbers (coefficients). In this way a geometric problem can be translated into an algebraic problem and the methods of algebra brought to bear on its solution. Conversely, the solution of a problem in algebra, such as finding the roots of an equation or system of equations, can be estimated or sometimes given exactly by geometric means, ., plotting curves and surfaces and determining points of intersection. In plane analytic geometry a line is frequently described in terms of its slope, which expresses its inclination to the coordinate axes。 the harnessing of accidents that occurred during the process of painting。 the use of huge canvases。s first oneman show in 1948 established him as a highly influential artist. His intensely plicated abstract paintings of the 1940s were followed by images of Woman, grotesque versions of buxom womanhood, which were virtually unparalleled in the sustained savagery of their execution. Painters such as Philip Guston and Franz Kline turned to the abstract late in the 1940s and soon developed strikingly original styles— the former, lyrical and evocative, the latter, forceful and boldly dramatic. Other important artists involved with the movement included Hans Hofmann, Robert Motherwell, and Mark Rothko。, and surrealism, became more personally expressive.

The choline is then available for reuptake into the nerve terminal. These same principles apply to cholinergic transmission at sites other than neuromuscular junctions, although the structure of the synapses differs. In the autonomic nervous system these include nervetonerve synapses at the relay stations (ganglia) in both the sympathetic and the parasympathetic divisions, and the endings of parasympathetic nerve fibres on nonvoluntary (smooth) muscle, the heart, and glandular cells。“黼”、“釜”都是形聲字，聲符相同，但意符不同，黼從鬲，釜從金?！按健焙汀懊嫛倍际切温曌?，聲符相同，但意符不同，唇從口，脣從肉。“野”是形聲字，“埜”是會意字。 （ 3）野（ 4）埜。“災”、“災”造字結(jié)構(gòu)不同。 適，本義是“前往”，通“謫”，是“罰”的意思。 亡，本義是“逃跑”，通“無”，是“沒有”的意思。 五、說明句中通假字的本義和所通之字及其意義 畔，本義是“田界”，通“叛”，是“背叛”的意思。 句中古字：沒，改變了意符寫作“歹”，成為今字“歿”。 句中古字：奉，增加了意符“扌”，成為今字“捧”。 句中古字：說，改變了意符寫作“忄”，成為今字“悅”。 句中古字：受，增加意符“扌”，成為今字“授”。 三、解釋句中黑體字的意義并寫出今字 責 債； 孰 熟； 禽 擒 景 影 四 、寫出句中的古字，并說明增加或改變了什么部件成為今字 句中古字：契，增加意符“钅”，成為今字“鍥”。 ３、本字與通假字的使用頻率問題。 ２、通假字與本字的對應關系。 改動古字的筆畫成為今字。 改變古字的義素成為今字。 今字的形體與古字的關系有幾種情況？（教材P187190 共五點） 今字的形體與古字的關系有以下五種情況： １、在古字的形體加義素形成今字。“礮”“砲”反映了這種兵器發(fā)石的特點。例如“醫(yī)”，繁體一作“毉”，一作“醫(yī)”，反映了醫(yī)療手段的不同。例如“戉”、“殳”、“鬲”反映了古代一些器物的形制?！皸怠睆哪?，那個時代有用木材制作的碗。 第一，古代一些器物用字的意符，反映了當時制作器物所用的材質(zhì)?，F(xiàn)代社會是工業(yè)經(jīng)濟時代，工業(yè)離不開金屬與化學材料，所以從金之字大量涌現(xiàn)。這種變化，大致上記載了中國社會在古代與現(xiàn)代的不同特點，上古時期，狩獵在人們的生活中占有很重要的位置，人們常常要與獸類打交道，所以犬部字非常多。例如，在《說文解字》中，馬部字有 123 個，牛部字 46 個，羊部字 28 個，犬部字 88 個，金部字 110，氣部字 3 個。 舉例說明漢字承載了社會物質(zhì)文化表現(xiàn)在哪些方面？（教材 P174175） ①漢字系統(tǒng)承載著物質(zhì)文化 甲骨文，金文、 縑帛文字等等的出現(xiàn)都各自反映了當時的一般物質(zhì)生產(chǎn)水平。人的文字閱讀活動是開發(fā)智力的重要活動之一，不同的文字對于人的大腦的作用是不一樣的。 人的大腦分為左右兩個半腦，左腦負責語言、數(shù)學、邏輯等方面的感知思維活動，右腦負責空間、音樂、想象、視覺等方面的感知思維活動。 閱讀不僅是學習的方法，而且也是工作的重要方法，不言而喻，對于需要閱讀的工作來說，高效率的閱讀，也就意味著高效率的工作。中文閱讀速度約是英文閱讀速度的 倍。中國社會很早就形成了統(tǒng)一的國家，有了完善的管理體制，這與文字的參與有著莫大的關系。漢字產(chǎn)生的根本原因在于管理事務的需要，反過來，漢字為國家的管理提供了最好的工具。而漢字對在中華大地上形成共同的漢語和共同的漢文化，產(chǎn)生了難以估量的作用，從而對中國的統(tǒng)一， 產(chǎn)生了巨大的作用。 第七、漢字是文化傳播最重要的載體。 第五、漢字是文化教育最重要的工具。 第三、漢字記錄了生產(chǎn)技術，從而有力地促進了物質(zhì)生產(chǎn)的發(fā)展。 在中華文明的發(fā)展過程中，漢字發(fā)揮了哪些重要的作用？（教材 P1591
